THREAD HOLDING AND CUTTING ATTACHMENTFOR SPOOLS.

SPECIFICATION forming part of Letters Patent N 0. 752,845, datedFebruary 23, 1904,

Application filed June 3, 1903. Serial No. 169,864. (No model.)

. To all whom it may concern:

Be it known that I, DAISY O. LAIRD, a citizen of the United States,residing at Des Moines, in the county of Polk and State of Iowa, haveinvented certain new and useful Improvements in Thread Holding andCutting Attachments for Spools, of which the following is aspecification.

The objects of my invention are to provide a device of simple andinexpensive construction that may be readily and quickly attached to anddetached from an ordinary spool of thread and with which the thread maybe conveniently and easily inserted in one end and there yieldingly heldand then drawn over a sharpened blade at the other end of the device andthere cut off, the severed end projecting some distance from the portionof the thread that is held, so that the severed end may be easilygrasped to be removed from the device, the parts being so arranged thatwhen the operator pulls upon the thread, as required to press it againstthe cutting device, this pull will not tend to draw the cutting devicefrom the spool nor to rotate it relative to the spool.

My invention consists in certain details in the construction,arrangement, and combination of the various parts of the device wherebythe objects contemplated are attained, as hereinafter more fully'setforth, pointed out in my claims, and illustrated in the accompanyingdrawings, in which Figure 1 shows an elevation of a spool of thread withmy device attached thereto and a portion of the thread being inserted inthe thread-holding end, part of the spool being broken away. Fig. 2shows a vertical central sectional view of a spool provided with myattachment, and Fig. 3 shows my improved device in perspective detachedfrom a spool and showing a thread held in one end thereof and inposition in the other end to be severed.

Referring to the accompanying drawings, I have used thereference-numeral 10 to indicate the spool, which is of the ordinaryconstruc is made of three parts.

The numeral 13 indicates one of the spoolgripping members, which ispreferably made of spring metal. Its upper end leis bent at an acuteangle to said body portion and is beveled at 15 to direct thread to passover and not become caught on said end. The part 14. is designed to restflat against one end of the spool.

The numeral 16 indicates a spool-gripping portion similar to the part 13and also pro vided with a top part 17, arranged at an acute angle to thebody portion and designed to lie flat against one end of the spool.

The third part of my improvement comprises a flat piece of metal 18,connected by rivets with the parts 14; and 17. One end thereof lies fiatupon the part 17 and is provided with an upturned sharpened blade 19 atits end. The other end is inclined upwardly from the part 14: and formswith said part a yielding thread-gripping device. Its outer end isrounded at 20 and is somewhat shorter than the part 14, so that a threadmay be easily passed between them.

In practical use I attach the device to a spool of thread by forcing theparts 13 and 16 toward each other and then placing them in the openingin one end of the spool and forcing them downwardly in the opening untilthe parts 14 and 17 rest upon the end of the spool. When in thisposition, the spool-engaging ends are held by yielding pressure againstthe interior of the spool, so the device will be held in position. Whenit is desired to hold and cut the thread, the operator passes the threadfrom a point near the blade 19 over on top of the spool, then on top ofthe end 14: under the rounded end 20. The thread is then drawn back overthe blade 19 and the operator pulls the thread downwardly over saidblade, thus severing it and yet not pulling upon the device in such away as to draw it from the spool nor twist it in the spool. As soon asthe thread is severed the loose end immediately withdraws fromengagement with attachment for spools, comprising two springmetal partswith their lower ends diverging from each other and designed to enter anopening in a spool and their upper end portions designed to lie flat ontop of a spool,

her to enter an opening in a spool and yieldingly engage the sides ofsaid opening, and a top piece riveted to said heads near their centralportions, having one end shorter than its adjacent head and rounded andforming with said head a narrow tapered opening, the other end portionresting on top of the other head and having an upturned end sharpened atits top, substantially as and for the purposes stated.

DAISY c. LAIRD.
